Disclaimer: As EPA has indicated in EIIP documents, the choice
of methods to be used to estimate emissions depends on how the estimates
will be used and the degree of accuracy required. Methods using site-specific
data are preferred over other methods. These documents are non-binding
guidance and not rules. EPA, the States, and others retain the discretion
to employ or to require other approaches that meet the requirements of
the applicable statutory or regulatory requirements in individual circumstances.

Draft Volumes and Chapters

Vol 8, Estimating Greenhouse Gas Emissions

This volume of the EIIP guidance is undergoing
revision to (1) increase consistency with the national inventory of
GHG emissions and sinks, (2) incorporate state-level data sources,
methods and emission factors where applicable, (3) update the text
and examples for clarity, and (4) to include references to a MS ExcelŽ
based tool designed to assist states in the estimation of emissions.
Substantive revisions include a number of methodological improvements
and improved compatibility with international inventory guidelines
and the Good Practice Guidance published by the Intergovernmental
Panel on Climate Change (IPCC) The revised guidance is in final draft
form and is currently undergoing review. To receive a copy of the
draft guidance and the companion State Inventory Tool, please contact
